The Anatomy of a Good Prompt
Effective prompts typically include these elements:
The CRISPE Framework
Bad vs Good Prompts
Bad Prompt:
"Write about marketing"
Too vague, no context or direction
Good Prompt:
"You are an experienced digital marketing consultant. Write a 500-word blog post about email marketing best practices for small e-commerce businesses. Use a conversational but professional tone. Include 5 actionable tips with examples. Format with headers and bullet points."
Clear role, context, format, and constraints
Advanced Prompting Techniques
Chain of Thought Prompting
Ask the AI to think step-by-step for complex problems.
"Solve this problem step by step. First, identify the key factors. Then, analyze each factor. Finally, provide your recommendation with reasoning."
Few-Shot Learning
Provide examples of the output you want to guide the AI's response format.
"Convert these sentences to professional tone:
Input: 'Hey, can you do this asap?'
Output: 'Could you please prioritize this task?'
Input: 'That idea is bad'
Output: 'I have some concerns about this approach.'
Now convert: 'I don't get it'"
Role-Based Prompting
Assign a specific persona to get expert-level responses.
"You are a senior software engineer with 15 years of experience in Python and database optimization. Review this code and suggest performance improvements..."
Constraint Setting
Set clear boundaries for more focused output.
"Explain quantum computing. Constraints: Use only analogies from everyday life. Avoid technical jargon. Keep it under 200 words. Suitable for a 10-year-old."
